Product description:

DK40 mine fan product performance and technical parameters
1, a new generation of energy-saving fan of mine K series, mainly used in metal surface or underground mines fans call the shots, auxiliary fan ventilation, ventilation can be used for other occasions.
2; The main properties of the series of energy-saving fan; technical indicators are as follows:
(1) series machine number: №7 ~ №26;
(2) Series Speed: 1450980730 r / min;
(3) air volume range: 2.0 ~ 164.2m3 / s;
(4) The total pressure range: 38 ~ 3819pa;
(5) Power range: 1.1 ~ 500kW;
(6) The efficiency of the fan: K-type single-stage total pressure efficiency η = 94%.
DK type of rotary hydrostatic efficiency η = 86%;
(7) Operating Noise: LA≤85dB (A).
3, the product from the DK40, DK45, K40, K45 and other mine fan composition, K40, K45 series auxiliary fans the most simple structure of the motor and impeller drive directly connected by the collector, the main body and the diffuser and other components. efficient use of new twisted blade airfoil, installation angle adjustable, laying steady flow loop device to make aerodynamic performance curve without hump, can be equipped with axial movement of the wheels on the base. Therefore, an efficient low noise, efficient wide area, stable performance simple structure, easy to install, and easy to use. DK40, DK45 series main fan using the same model, with the power of two K40, K45-type fan butted together, two counter-rotating impeller each other, constitute a rotating structure They are compared with the long axis of the drive-type main fan has a high efficiency, low resistance run innings, save construction investment, etc., with significant energy savings.
